ROPE-CLAMP.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed November 28,1904. Serial No. 234,462.

To all whom it may concern:

Be it known that I, DANIEL S. KRANCH, a citizen of the United States,residing at Barnesville, in the county of Schuylkill and State ofPennsylvania, have invented certain new and useful Improvements inRope-Clamps, of which the following is a specification.

transmission where it is desirable to have no promi-' nent projectionson the surface of the clamps or rope couplings and where it is importantto provide against the edge of the clamp cutting the rope.

Having in view these objects and others of general utility, I havedesigned the clamp hereinafter described in detail and which isillustrated in the accompanying drawing which forms a part of thisapplication and in which:

Figure l. is an elevation of the clamp applied to the end of a piece ofrope, and Fig. 2 is a view of the clamp detached and open.

Referring to the drawings in detail, it will be seen that the clamp ismade up of two complementary sections a, a which correspond in alldetails, and same are pivoted together at b. Each section consists of asemi-cylindrical main portion a an extension a and a hook-shaped neck (1the pivot extending through the latter. On the inner wall of the mainportion of each section a semicylindrical rib a is formed which incross-section is the shape of an inverted V. The inner wall of theportions a are cut away or rounded out as at a so that when the sectionsare closed on the end of a rope an eye is formed which is adapted 'to beengaged by the neck portion of a corresponding clamp on the opposite endof the rope. The

extensions are further cutaway to form a flat face a so that when twosections are assembled and pivoted together the faces a lie on eachother.

Rivet 0r bolt holes a extend transversely through the walls of theportions a and when the rope c is inserted in the clamp, a bolt or rivet(.Z is passed through the sections and the rope, thus positivelysecuring the latter in the clamp.

It will be noted that the outer walls of the sections taper inwardlyfrom their pivoted ends, and that the inner walls from the ribs a flareoutwardly, such con struction providing for the necessary strength ofthe clamp at the eye and for preventing the rope from being drawn at asharp angle over the outer edge of the clamp when the latter passesaround pulleys and the consequent cutting of the outer strands of therope it being understood that the diameter of the rope is sufficientlyless than the inner diameter of the clamp at its edge to permit of somelateral play by the rope.

The ribs a are pressed into the rope by drawing together the clampsections, thus affording additional positive gripping action.

Having thus described my invention what I claim and desire to secure byLetters Patent, is:-

A rope clamp consisting of two corresponding comple mentarysemi-cylindric members each comprising a hookportion having a flat faceon one side and a rounded face on the opposite side, and a shoulder atthe base of the hook, and comprising a clamping portion having graduallyoutwardly tapering walls from the hook-end to the outer end, saidclamping portion also having a seu1iannular rib projecting; from itsinner wall, each of said members also having a cut-away portion betweenits hook and clamping portions, whereby, when said members areconnected, an eye will be formed in communication with the tubularclamping portion, and means for pivotally connecting the hooks withtheir flat faces in juXta-position, and means for rigidly connecting theclamping portions of said incinoers together.

In testimony whereof I atlix my signature in presence of two witnesses.
